In my view, one of the strongest arguments for objective morality is the existence of qualia. It shows that the Universe can be made to contain weirder stuff than objectively existent goals. If you can take complex, fundamentally subjective facets of cognition and turn them into objectively existent qualia, why can't you do the same thing with goals? It would appear to be a lot simpler, on the surface at least. In fact, given the qualia of pleasure, one could make a good case that it's happened already.

Precisely.
If you haven't done so already, I strongly suggest you check out the section on "Logic" in the site that appears in my signature.
What in the name of skeg happened here, Eliezer? Why does Zeb need to visit your logic site? Have you read it recently? I think I'm in the twilight zone........
